Sometimes men are faced with impossible odds, hopelessly outnumbered or facing a merciless enemy with better weapons or other overwhelming advantages. Occasionally these terrible odds are overcome, as in the battles of Rorke’s Drift and Stalingrad. Other times, such as at the Alamo or Thermopylae, the bravest stood and fought to the bitter end with valiant efforts worthy of remembrance.
Never mind the legalities of the situation. Never mind morality either. Just answer the pragmatic question: Is it ever a good idea to start a nuclear war? Because that's the notion that U.S. President Donald Trump is actually playing with.
President Trump has egged on a new arms race. Russia violated weapons treaties to upgrade its nuclear arsenal. North Korea is developing long-range missiles and practicing for nuclear war — and the US military is considering preemptive attacks on the isolated nation’s military facilities.
Meanwhile, nuclear terrorism and dirty bombs remain a sobering threat.
